To make more money, and to access the larger audience the other social networks provide.

Vine, once a top 50 app in the iTunes store, has now dropped to 200. Nearly 5,000 of Vine's stars with more than 15,000 followers have left the platform, as determined by Markerly, a company dealing with social media influencers. The average number of views on the top 10 Vine accounts have also decreased by 29% this year, reports The Wall Street Journal.

Will Stickney, Twitter spokesperson and a contributor to Vine, told the Journal that Twitter's top priority this year is to give the Vine creators better tools, preventing them from migrating.

"Vine... continues to be a place where creative trends start and explode across the web," he said Vine CEO Joe Gagliese, on the other hand, has actually encouraged clients to start using Facebook because he thinks that Vine does not have a strong advertising model in place yet.

Gagliese believes that Facebook analytics are more robust, and its strong video features make for better monetization opportunities.
